In fact, "delay" is a form of expression with great aesthetic significance, and there is an aesthetic phenomenon of "delay" in almost all kinds of literary creation. Compared with novels and plays, poems are short in length, and it is necessary to express rich thoughts and feelings in extremely short words, which requires the use of "procrastination", because an inch of water can also make waves, and a foot can be thousands of miles apart.
Short poems also need twists and turns and profound meaning. Bai Juyi's Pipa Journey describes the superb skills of pipa girls in playing pipa. Poets mainly use a variety of rhetorical devices, and use a lot of metaphors and synaesthesia to describe the moving melody of music, which is vivid and superb.
After the positive description, the sudden use of "procrastination" makes the poem steep and waves, creating a new scene-"East boat is quiet in the west, we see the white autumn moon entering the river!" At first glance, these two poems are all about scenery, which seems to have nothing to do with the description of playing the pipa. In fact, these two poems further describe superb performance skills. Just write from another side, that is, from the performance effect.
Bai Juyi, unconventional, found another way, not by following it, but by strokes. He wrote that the east boat and the west boat were quiet, and on the wide river, only the autumn wind rustled and the reeds rustled, and only a bright moon hung in the sky. Under the moonlight, autumn water is like practice! Besides, it is silent! What a wonderful state it is-it is precisely because the pipa music is beautiful and moving that I feel "if there is a sound of nature in my ear". The audience has been immersed in this beautiful music atmosphere, and their hearts are still at the end of the song, immersed in it, and there is no response. It can be said that "I forgot everything, only this song"! Bai Juyi used "procrastination" to set off unparalleled music and wrote the audience's unresponsiveness.
